What is My Reaction Time?

(In the experiment we only showed one person's hand, but we tested both.)

What is is:This is an experiment that shows me which hand has a faster reaction time.
Variables of this experiment:
      Variables
      * The distance of the thumb and pointer finger
      * The thumb and pointer finger is aligned with the 0,
      * Gravity does the work for the ruler to fall
      * The other person has to let go of the ruler unexpectedly.
      * Non-Dominant and Dominant hand

Hypothesis
      * I think that the reaction time of the dominant hand will be faster than the non-dominant hand as your right hand is used for more things.

Variables that I will try to keep the same:
      * The distance of the thumb and pointer finger
      * The thumb and pointer finger is aligned with the 0,
      * Gravity does the work for the ruler to fall
      * The other person has to let go of the ruler unexpectedly.

Sample size:
About 5! people, or 120 people, right handed and left handed. That is because if everyone was right handed, you wouldn't know about the other people who were left handed. Also, you would need 10 trials for each person.


Type of data: Quantitative

Procedure (Also in video): 
1. Take a ruler that is 30 cm long and a rubber band to start the experiment.
2. Place your rubber band between your thumb and pointer finger, rubber band slightly tight.
3. Slowly take your fingers out of the rubber band , and place them right at the 0 of the ruler.
4. Your partner places their fingers exactly on top of the 30.
5. Your partner drops the ruler unexpectedly, leaving gravity to let it fall
6. The amount of cm you catch it at is your reaction time for your one hand.
7. Repeat this several times for the same hand.
8. Do steps 2-7 again for the hand you have not tested.
9. That's it!

The results of the experiment

and the results for my partner,

Conclusion: The reaction time of the dominant hand will be faster than the non-dominant hand.

    Why: The evidence clearly showed that, since that I am right handed,  and the amount of cm is lower for my right hand, my right hand has the faster reaction time.
It is the same with my partner.

Hi everyone, here is the fitness video I made with my group in PE!

How Would I Be in Drama?

8.75

TEN is a person who is dying to hit the stage on day one of drama and would willingly perform in front of all of 6th grade right NOW! ONE is a person who would rather be ANYWHERE but the stage and would prefer to be wrapped up in a blanket back in their bed hugging their teddy bear. On this scale of one to ten, I would be a 8.75 because I am completely comfortable with the stage, be it music or pubic talking, but if I had to do a play or dance on stage I would.... well lets say I would be terrible. I have hand a lot of experience on the stage ; however, most of it was just playing the piano. I feel a lot more comfortable on the stage using an instrument, as it gives something that I can focus on besides the audience. For public speaking, I'm not so keen, but I don't have a fear of it. That's why I'm an 8.75.

Sportsmanship

 I think the main definition of sportsmanship is to treat the other teammates with respect and to play fairly by the rules. You should demonstrate sportsmanship while playing sports as it shows you respect the other team, and playing by the rules would help the game be a fair one. In floor hockey, I demonstrated sportsmanship by respecting the other teams efforts, complementing them for what they did well, and playing fairly by the rules.  A few ways everyone can demonstrate sportsmanship in everyday life is to congratulate people when they do well on something, if playing a board game like Monopoly - do not steal money, and to talk politely to others during an event.  

This video is a good example of sportsmanship as the umpire that made a bad call didn't storm away and not come back, instead, after the game, he came to the person and apologized and ! gave him a hug !

The Components of Physical Fitness

Definition of physical fitness -- you have the energy and strength to participate in a variety of activities.

Cardiorespiratory Endurance

• You heart, blood vessels and lungs are able to distribute nutrients and oxygen and remove waste efficiently.
• Regular exercise improves cardiorespiratory endurance

Muscular Strength

• The ability of a muscle to produce force
• Amount of weight you can lift is a measure of this.

Muscular Endurance

• Ability of muscles to work for an extended time
• Requires walking, rowing, or raking leaves

Flexibility

•  Ability to move a joint through its entire range
• Stretching exercises can help with this

Body Composition

• The amount of fat tissue in your body compared to the amount of lean tissue
• Too much or too little of body fat can lead to health problems.

Wellness Project

Hello readers, here is my wellness project slides. I think it went quite well because I got some of my friend's feedback on google forms for my presentation and speech and got quite good results. It worked out quite well, and I hope in the future everyone will use these fitness tips. Thanks!

Pellagra

Here are the answers to the "Pellagra" questions.

1a. He observes first hand where the severe cases of the pellagra are. He then visited a prison with lots of cases of pellagra. This helped him to develop his hypothesis as he found all the people getting pellagra were poor and had a terrible diet.

1b. He found that in orphanages and prisons only the kids and the prisoners contracted pellagra, not the teachers from the orphanages or the staffs from the prison, so it couldn't be caused by germs as they do not know of status boundaries.

2a. His hypothesis about the cause of pellagra was that it was caused by a lack of vitamins, like scurvy.

2b. He conducted an experiment on 11 prisoners. Before the experiment, the prisoners were eating fruits and vegetables from the prison garden. Goldberger started feeding them only corn and bread, and in the end 7/11 of the people that ate corn contracted pellagra, but when the prisoners were allowed to eat fruits and vegetables their pellagra healed. This provided evidence that proved his hypothesis as when he took away vitamins, the inmates got pellagra, but when they had vitamins (fruits and vegetables) again, they got better.

2c. He could have provided more information like telling the people at that time what particular vitamin, when lacked, caused pellagra. This would have acted like a "medicine" and people would have believed in it more. Or, he could have said people need to have a lot of vitamins to cure pellagra instead of saying that it was caused by a lack of vitamins.

5. I think this was a bad idea as conducting the experiment on humans would actually be quite cruel and sometimes might get the people in the experiment insane and confused. They would also suffer a terrible 6 months of their life suffering pellagra because of the diet. I would only try to give it to one person that is willing to suffer pellagra for science's sake, or just give it to another animal entirely. This would be a lot better as not so many humans would have to contract the pellagra disease.
